BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to digital video. More particularly, the present invention relates to digital video rendering.

2. Background Art

Modern commodity PC hardware and videogame consoles are often equipped with sufficient processing capability to enable high-resolution real-time three-dimensional graphics rendering. Even portable devices such as mobile phones and handheld gaming systems are often equipped with scaled down real-time three-dimensional graphics support. Such low-cost commodity graphics processing hardware has enabled a wide variety of entertainment and productivity applications to support enhanced visual presentations for greater user engagement and enjoyment.

In particular, real-time three-dimensional graphics rendering has served as a catalyst for the growth of competitive multiplayer games, which can often simulate real life games such as sports. The rising popularity of such competitive videogames has lead to large game tournaments, videogame celebrity personalities, and even nationally broadcasted television programs focusing on such competitive videogame matches. However, the limitation of videogames having to render graphics in real-time to react to user input places practical limitations on the graphical quality of the final result. Thus, an ordinary person can determine from a cursory visual examination that only a computer rendering is being shown, and not an actual real life game. As a result, ordinary viewers may lose interest in viewing such videogame matches, since they are aware that what they are seeing is merely a computer rendering.

Accordingly, there is a need to overcome the drawbacks and deficiencies in the art by providing a way to present videogames using real-time three-dimensional graphics without exposing the graphical limitations of real-time rendering.

SUMMARY OF THE INVENTION

There are provided systems and methods for integrating a virtual rendering system and a video capture system using flexible camera control to provide an augmented reality for videogame broadcast programming, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.

DETAILED DESCRIPTION OF THE INVENTION

The present application is directed to a system and method for integrating a virtual rendering system and a video capture system using flexible camera control to provide an augmented reality for videogame broadcast programming. The following description contains specific information pertaining to the implementation of the present invention. One skilled in the art will recognize that the present invention may be implemented in a manner different from that specifically discussed in the present application. Moreover, some of the specific details of the invention are not discussed in order not to obscure the invention. The specific details not described in the present application are within the knowledge of a person of ordinary skill in the art. The drawings in the present application and their accompanying detailed description are directed to merely exemplary embodiments of the invention. To maintain brevity, other embodiments of the invention, which use the principles of the present invention, are not specifically described in the present application and are not specifically illustrated by the present drawings.

FIG. 1 presents a system for integrating a virtual rendering system and a video capture system using flexible camera control to provide an augmented reality for videogame broadcast programming, according to one embodiment of the present invention. Diagram 100 of FIG. 1 includes virtual rendering system 110, video capture system 130, master controller 150, composite render 155, live broadcast link 156, and displays 157-159. Virtual rendering system 110 includes rendering engine controller 111, auxiliary rendering engine 112, slave rendering engines 113 a-113 b, input devices 114 a-114 b, and virtual environment 120. Virtual environment 120 includes virtual cameras 121 a-121 b. Virtual camera 121 a includes data 122 a. Virtual camera 121 b includes data 122 b. Video capture system 130 includes camera motion controller 131 and real environment 140. Real environment 140 includes robotic cameras 141 a-141 b. Robotic camera 141 a includes data 142 a. Robotic camera 141 b includes data 142 b.

Rendering engine controller 111, auxiliary rendering engine 112, slave rendering engine 113 a, and slave rendering engine 113 b may each execute on several separate servers, each comprising standard commodity PC hardware or a videogame console system. Alternatively, the engines of virtual rendering system 110 may be consolidated into a single server, or distributed remotely across a network to minimize the amount of necessary on-site hardware. Rendering engine controller 111 may coordinate control and data sharing between the different rendering subsystems, as shown in FIG. 1. Thus, rendering engine controller 111 may represent a shared server used by slave rendering engines 113 a-113 b, which represent player clients. Auxiliary rendering engine 112 may provide static graphics overlays and other graphical effects and assets that do not require input from virtual environment 120. Slave rendering engines 113 a-113 b each control virtual cameras 121 a-121 b respectively to receive a virtually rendered feed of virtual environment 120.

Furthermore, slave rendering engine 113 a may output a view of virtual environment 120 defined by virtual camera 121 a to display 158, whereas slave rendering engine 113 b may output a view of virtual environment 120 defined by virtual camera 121 b to display 159. As a result, a first user client or player may use display 158 to react to virtual environment 120 using input device 114 a, whereas a second user client or player may use display 159 to react to virtual environment 120 using input device 114 b. Input devices 114 a-114 b may comprise, for example, a joystick, a mouse, a keyboard, or a combination of such input devices. After slave rendering engines receive user input from input devices 114 a-114 b, modifications to virtual environment 120 may be made, such as the movement of virtual objects like virtual players or virtual balls.

Data 122 a-122 b describing the configuration of virtual cameras 121 a-121 b within virtual environment 120 may each include, for example, position data such as three-dimensional coordinates, camera field of view orientation data such as camera angle, focal length and focus distance, movement data such as a motion path or velocity and acceleration, and camera characteristics such as lens parameters, camera size, center of lens, and other camera modeling details. Three-dimensional coordinates between virtual environment 120 and real environment 140 may be defined using a common frame of reference, such as setting a particular corner of a field or a particular landmark as a common (0, 0, 0) coordinate. The motion path may then describe the changing of the above data parameters with respect to time, such as the three-dimensional coordinates with respect to time or the camera field of view with respect to time. Slave rendering engines 113 a-113 b may then modify data 122 a-122 b respectively to control camera paths for respective virtual cameras 121 a-121 b.

Although virtual rendering system 110 of FIG. 1 depicts only two slave rendering engines each controlling exactly one virtual camera, alternative embodiments may use any arbitrary number of slave rendering engines to control any arbitrary number of virtual cameras. More specifically, each slave rendering engine may control more than one virtual camera. Similarly, although video capture system 130 of FIG. 1 only depicts two robotic cameras, alternative embodiments may use any arbitrary number of robotic cameras to be controlled by camera motion controller 131 of video capture system 130. In this manner, the composite rendering system shown in FIG. 1 can be scaled to as many camera angles and viewpoints as desired, in either virtual environment 120 or real environment 140.

Real environment 140 corresponds to an actual physical environment represented by virtual environment 120. For example, real environment 140 might comprise an indoor or outdoor sports field or stadium, a golf course, a natural environment, an urban environment, or any other locale. Although examples have so far focused on sports entertainment applications, other focuses such as educational or informational applications may also benefit from this use of augmented reality. Virtual environment 120 may then be created using manual three-dimensional environmental modeling, automated photographic or video extrapolation, or some other manual or automated method.

Master controller 150 may direct virtual rendering system 110 to control virtual cameras 121 a-121 b according to particular parameters, and also direct video capture system 130 to control robotic cameras 141 a-141 b using the same parameters. The particular parameters of camera behavior might be dictated by manual control, by tracking the motion of a particular object or focusing on a particular scene in either virtual environment 120 or real environment 140, by replaying a previously recorded pattern of movement or another predetermined path, or by using some other criteria. Tracked objects may include, for example, a ball or a participating player of a game such as a sports match, and may be virtual or real. Once the virtual and robotic cameras are properly configured by appropriately programming the motion paths of data 122 a-122 b and 142 a-142 b, master controller 150 may then query virtual rendering system 110 for virtually rendered feeds and video capture system 130 for video capture feeds. Master controller 150 may then act as a rendering controller by combining the feeds smoothly using standard broadcast key technology such as chroma key or key/fill to generate composite render 155, which includes real and virtual feed elements arranged in a specific desired manner for broadcast over live broadcast link 156 to display 157. Live broadcast link 156 may comprise, for example, a satellite uplink to a television studio, from where the broadcasted material is disseminated to the general public. Display 157 may then represent, for example, a television of a viewer watching the broadcast.

FIG. 2 presents a diagram of a robotic camera path configured to match a virtual camera path, according to one embodiment of the present invention. Diagram 200 of FIG. 2 includes virtual environment 220 and real environment 240. Virtual environment 220 includes virtual camera 221, virtual camera path 223, virtual object 225, and virtual object path 226. Real environment 240 includes robotic camera 241 and robotic camera path 243. With regards to FIG. 2, it should be noted that virtual environment 220 corresponds to virtual environment 120 from FIG. 1 and that real environment 240 corresponds to real environment 140 from FIG. 1. Moreover, although FIG. 2 only depicts a single virtual camera and a single robotic camera for simplicity, alternative embodiments may use multiple virtual cameras and multiple robotic cameras.

As previously discussed in FIG. 1, master controller 150 may direct video capture system 130 to control robotic cameras similarly to virtual cameras in virtual rendering system 110. FIG. 2 shows an example of this manner of control, where robotic camera 241 is programmed to follow the movements of virtual camera 221. For example, virtual camera 221 may be programmed to focus on the movement of virtual object 225 following virtual object path 226. Thus, virtual camera 221 may follow virtual camera path 223, with camera orientation following virtual object path 226 as indicated by the dotted arrows. Virtual camera path 223 may then be recorded and programmed into robotic camera 241 of real environment 240, so that robotic camera 241 can follow robotic camera path 243 mirroring virtual camera path 223. Robotic camera 241 may comprise, for example, a gantry supported fly-by camera, a programmable motion control camera, or another camera system supporting programmable movement.

As shown in FIG. 2, the camera orientation of robotic camera 241 moves as if it were following virtual object path 226 within real environment 240, even though there is no corresponding real object for virtual object 225 in real environment 240. By using the system described above in FIG. 1, robotic camera 241 can thus be synchronized to the camera movements of virtual camera 221. Composite rendering of real and virtual environments, also known as “augmented reality”, is thus facilitated, as the camera views in virtual environment 220 and real environment 240 can be matched according to any desired virtual camera path, opening up limitless possibilities for dynamic camerawork.

The example shown in FIG. 2 might be used, for example, to present a dynamic panning camera view showing a hypothetical ball pass defined by virtual object 225 following virtual object path 226, even though such a ball pass never happened in real environment 240. The ball pass might be initiated, for example, by a user input originating from input device 114 a or 114 b in FIG. 1. Thus, a composite render might show a real sports field or stadium background in a video feed captured from real environment 240, but with virtual players and a virtual ball rendered in virtual environment 220. Thus, the composite render can provide a realistic camera fly-by with photo-realistic background elements from real environment 240 and a virtual players and a virtual ball rendered from virtual environment 220. In this manner, a three-dimensional composite render appearing to have largely photo-realistic quality can be provided to viewers even within the constraints of real-time computer rendering.

FIG. 3 presents a diagram of a composite render being generated, according to one embodiment of the present invention. Diagram 300 of FIG. 3 includes virtual rendering system 310, virtually rendered feeds 315 a-315 b, video capture system 330, video capture feeds 335 a-335 b, master controller 350, composite render 355, live broadcast link 356, and display 357. With regards to FIG. 3, it should be noted that virtual rendering system 310 corresponds to virtual rendering system 110 from FIG. 1, that video capture system 330 corresponds to video capture system 130, that master controller 350 corresponds to master controller 150, that composite render 355 corresponds to composite render 155, that live broadcast link 356 corresponds to live broadcast link 156, and that display 357 corresponds to display 157.

As shown in FIG. 3, virtual rendering system 310 provides master controller 350 with virtually rendered feeds 315 a-315 b, while video capture system 330 provides master controller 350 with video capture feeds 335 a-335 b. For example, video capture feed 335 a might correspond to a feed generated by robotic camera 241 in FIG. 2, whereas virtually rendered feed 315 a might correspond to a feed generated by virtual camera 221 in FIG. 2. Virtually rendered feed 315 b may correspond to a feed created by an overhead virtual camera providing a bird's eye overview of virtual environment 220 from FIG. 2, whereas video capture feed 335 b may correspond to a feed created by an overhead robotic camera providing a bird's eye overview of real environment 240 from FIG. 2.

Master controller 350 may then combine virtually rendered feed 315 a and video capture feed 335 a for an augmented reality fly-by scene and also combine virtually rendered feed 315 b and video capture feed 335 b for an augmented reality bird's eye overview scene. As previously discussed, master controller 350 may use standard broadcast key technologies to combine the different feeds smoothly so that the juxtaposition of real and virtual elements is visually unobtrusive. Master controller 350 may then use these combined scenes in composite render 355 through various presentation methods such as split screen, cascaded or tiled frames, “picture-in-picture”, three-dimensional surfaces, and other formatted layouts. Master controller 350 may then forward composite render 355 over live broadcast link 356 for showing on display 357. Master controller 350 may repeat the above process of generating composite render 355 in a periodic manner, such as 24, 30, or 60 times per second or higher in order to accommodate a desired video broadcasting framerate.

Although FIG. 3 only shows a single composite render 355, alternative embodiments may use several composite renders. For example, master controller 350 may generate multiple composite renders to provide different camera views for multiple broadcast channels, to customize based on a target broadcast region or audience demographics, to focus on a particular team in a sports match, or to support any other broadcasting application that may require multiple concurrent video streams. By adding additional slave rendering engines and robotic cameras, augmented reality rendering systems can be readily scaled and configured to support large-scale projects.

FIG. 4 shows a flowchart describing the steps, according to one embodiment of the present invention, by a virtual rendering system and a video capture system may be integrated for outputting a composite render of an augmented reality to a display for videogame broadcast programming. Certain details and features have been left out of flowchart 400 that are apparent to a person of ordinary skill in the art. For example, a step may comprise one or more substeps or may involve specialized equipment or materials, as known in the art. While steps 410 through 470 indicated in flowchart 400 are sufficient to describe one embodiment of the present invention, other embodiments of the invention may utilize steps different from those shown in flowchart 400.

Referring to step 410 of flowchart 400 in FIG. 4 and diagram 100 of FIG. 1, step 410 of flowchart 400 comprises receiving input data from a plurality of clients using input devices 114 a-114 b for modifying virtual environment 120 presented on displays 158-159 using slave rendering engines 113 a-113 b of virtual rendering system 110. For example, a player for the offense of a sports game may react to display 158 using input device 114 a to provide input data, whereas a player for the defense of a sports game may react to display 159 using input device 114 b. Slave rendering engines 113 a-113 b may then interpret the received user input to modify virtual environment 120, for example by setting into motion virtual players and a virtual ball as virtual objects within virtual environment 120. Additionally, data 122 a and data 122 b may be updated so that virtual cameras 121 a-121 b follow the focus of the user-initiated actions within virtual environment 120.

Referring to step 420 of flowchart 400 in FIG. 4 and diagram 100 of FIG. 1, step 420 of flowchart 400 comprises obtaining, from virtual rendering system 110, data 122 a of virtual camera 121 a in virtual environment 120. As shown in FIG. 1, master controller 150 may query rendering engine controller 111 for a virtual camera configuration concerning virtual camera 121 a. Rendering engine controller 111 may then determine that slave rendering engine 113 a controls virtual camera 121 a, and correspondingly send a request to slave rendering engine 113 a to retrieve data 122 a. Data 122 a may then be retrieved by slave rendering engine 113 a, for relay back to master controller 150 via rendering engine controller 111. As previously described, data 122 a may contain various information concerning the configuration of virtual camera 121 a such as three-dimensional position and movement, camera focus and view, camera model parameters, and other details.

Referring to step 430 of flowchart 400 in FIG. 4 and diagram 100 of FIG. 1, step 430 of flowchart 400 comprises programming video capture system 130 using data 122 a obtained from step 420 to correspondingly control robotic camera 141 a in real environment 140. For example, master controller 150 may instruct camera motion controller 131 to program values into data 142 a to match data 122 a as closely as possible. As previously discussed, data 122 a may include three-dimensional coordinates and camera field of view with respect to time. Assuming virtual camera 221 and robotic camera 241 correspond to virtual camera 121 a and robotic camera 141 a, the result of setting data 142 a to match data 122 a may be manifested by robotic camera path 243 mimicking virtual camera path 223, as shown in FIG. 2.

Referring to step 440 of flowchart 400 in FIG. 4, diagram 200 of FIG. 2, and diagram 300 of FIG. 3, step 440 of flowchart 400 comprises capturing, from video capture system 330, video capture feed 335 a of real environment 240 using robotic camera 241. Since the motion path of robotic camera 241 was previously programmed in step 430, step 430 results in master controller 350 receiving video capture feed 335 a comprising fly-by footage according to robotic camera path 243.

Referring to step 450 of flowchart 400 in FIG. 4, diagram 200 of FIG. 2, and diagram 300 of FIG. 3, step 450 of flowchart 400 comprises obtaining, from virtual rendering system 310, virtually rendered feed 315 a of virtual environment 220 using virtual camera 221 and showing the modifying of virtual environment 220 in step 410. As previously discussed, user input from step 410 may affect data 122 a-122 b, which may in turn affect the movement of the virtual cameras and thus virtual camera path 223. As shown in FIG. 2, virtual camera path 223 is defined as an arc with the camera field of view following virtual object 225 as it progresses through virtual object path 226. For example, by a user may initiate the movement of virtual object 225 by pressing a button mapped to “pass ball” on input device 114 a. Thus, master controller 350 may receive virtually rendered feed 315 a comprising fly-by footage according to virtual camera path 223, wherein the feed includes a rendering of virtual object 225 moving through virtual environment 220 as initiated by the input data of step 410.

Referring to step 460 of flowchart 400 in FIG. 4 and diagram 300 of FIG. 3, step 460 of flowchart 400 comprises rendering composite render 355 by processing video capture feed 335 a from step 440 and virtually rendered feed 315 a from step 450. As previously discussed, master controller 350 may accomplish step 460 using standard broadcast key technology such as chroma key or key/fill techniques to isolate and combine components from each feed to produce a result with a smooth visual juxtaposition of real and virtual elements.

Referring to step 470 of flowchart 400 in FIG. 4 and diagram 300 of FIG. 3, step 470 of flowchart 400 comprises outputting composite render 355 from step 460 to display 357. As shown in FIG. 3, master controller 350 may send composite render 355 using live broadcast link 356, which might comprise a satellite uplink to a broadcast station for public dissemination. Eventually, composite render 355 shows on display 357, which might comprise the television of a viewer at home.

While the above steps 410-470 have been described with respect to a single virtual camera, a single robotic camera, and a single composite render, steps 410-460 may also be repeated as necessary to support multiple virtual cameras, multiple robotic cameras, and multiple composite renders, as previously described. Moreover, more than two input devices might be supported for games having more than two concurrent players. In this manner, the described rendering system can be flexibly scaled to larger projects by increasing the number of slave rendering systems and robotic cameras to handle additional feeds in real-time.

In this manner, virtual games such as competitive sports games can be enhanced with high-impact augmented reality segments by leveraging real environmental footage from synchronized motion control camera systems. This can provide networks with a competitive advantage by drawing in and retaining greater viewership by providing compelling augmented reality content while requiring only minor additional infrastructure outlays over standard rendering systems. Since commodity hardware parts are used, expensive proprietary systems and vendor lockout may be avoided, further reducing total cost of ownership.

From the above description of the invention it is manifest that various techniques can be used for implementing the concepts of the present invention without departing from its scope. Moreover, while the invention has been described with specific reference to certain embodiments, a person of ordinary skills in the art would recognize that changes can be made in form and detail without departing from the spirit and the scope of the invention. As such, the described embodiments are to be considered in all respects as illustrative and not restrictive. It should also be understood that the invention is not limited to the particular embodiments described herein, but is capable of many rearrangements, modifications, and substitutions without departing from the scope of the invention.
